Trivial patch to change RUNTIME_DIR.

When updating sddm on Fedora 37 to sddm-0.19.0^git20230214.8f1e3df-1.fc37.x86_64, the warning:

| /usr/lib/tmpfiles.d/sddm.conf:6: Line references path below legacy directory /var/run/, updating /var/run/sddm → /run/sddm; please update the tmpfiles.d/ drop-in file accordingly.

is output.  The triggering entry is:

| # This contains X11 auth files passed to Xorg and the greeter
| d       /var/run/sddm   0711    root    root

It should be fixable by patching CMakeLists.txt's:

| # Set constants
| set(DATA_INSTALL_DIR            "${CMAKE_INSTALL_FULL_DATADIR}/sddm"                CACHE PATH      "System application data install directory")
| set(DBUS_CONFIG_DIR             "${CMAKE_INSTALL_SYSCONFDIR}/dbus-1/system.d"       CACHE PATH      "DBus config files directory")
| set(STATE_DIR                   "${CMAKE_INSTALL_FULL_LOCALSTATEDIR}/lib/sddm"      CACHE PATH      "State directory")
| set(RUNTIME_DIR                 "${CMAKE_INSTALL_FULL_LOCALSTATEDIR}/run/sddm"      CACHE PATH      "Runtime data storage directory")
                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| set(QML_INSTALL_DIR             "${QT_IMPORTS_DIR}"                                 CACHE PATH      "QML component installation directory")

but I have not tested the attached patch beyond verifying that /usr/lib/tmpfiles.d/sddm.conf then refers to /run/sddm.

This was previously reported as bugs #1748321 and #1795294.
